PROCESS: OF I'NLAYING DESIGNS ON GLASS.

Applicationl led' .Tune 14, 1924.

il'oaidly this invention relates toglass ornamentation, but it more especially comprehendsain improved method or process -tor inlaying: a predetermined design onl zgal-ass.

The principal. object ot this invention to prov-ide a simple `and eiicien-t process lor intaying a predetermined designer en'iblem in mother of pearl, gold clippings,l or other suitable material on glass for the ori-lamentat-:on o't' trays and ,t-helilre.

Another important object ot this invention is the' provision ot an improved process iter inlaying a predetermined design Oremblem on glass, .onefot the necessary steps in the process also providing' a back ground tor the design ot 'any contrasting or desired color.

Fig. l is a plan view of an emblem inlaid on glass in accordance with my improved process;

Fig. 2 is a cross section on the line 2 2- ot Fig. l.

am aware that many processes and methods have been evolved for effecting an ornamental inlaid. design on glass, but these, owing to a multiplicity of steps or intricate operations and amount oft time, labor and materials required haveproven either too costly or for other reasons more or less unsatisfactory, and to overcome such deficiencies and to provide a simple, etiicient and inexpensive process ot inlaying a predetermined design on glass or the like, one ot the necessary steps in the process also pro viding a. back-ground for the inlaid design oit any desired color7 that I evolved the `process forming the subject matter ot this invention.

The various steps or operations in my process for attaining the desired object, that is, an inlaid design or emblem on glass ivith a back-ground ot contrasting color, are as follows: tiret, a layer of tin foil or the like is carefully laid over the entire reverse surface ot the glass to be decorated; then a pattern of card board in the form of the design or emblem is superimposed on the tin toil and the latter is then cut with a sharp knife corresponding to the form of the pattern. Though I have preferably speciiied card board, any suitable form of pattern may be employed according to the particular requirements.

Serial No. 720,118.

The next step tollen-'ing' the above operation is to remove all the tin 'foilzexcept that representing the design by means el an ordinary knite or by any other suitable means, lea-ving a pattern on the glass in the terni ot the desired design or emblem 6, and border 6, When the latter is desired,atter which a coat ot paint 2 is applied to kcover the glass l and the tin 'toil representingthe design and the border. @ne or more coats oit this paint may be applied according,v to the larticular requirements, but as the first applic on represents the back-ground tor the design or emblem and covers all of the glass except that covered by the inlay, it may be ot' the desired color to contrast with the inlaid portions.

When the paint 2 applied as above described has dried the remaining tin foil is removed leaving an empty or channeled design and border 6 on the glass l. Then a coat. ot transparent varnish t is applied over the Whole glass including the empty design 6, atter which, the recessed design or emblem is inlaid With pearls 8, the interstices between the pearls, in the present instance, being lled Withl gold metal clippings of color sheet 5. Ot course, any suitable material or materials may be employed in lieu ot those above specified according` to the particular requirements, such inlaid materials then being pressed into the said empty design (i, and lirmly secured therein by the said transparent varnish Though it is not in many instances necessary, in others it has been found expedient to cover the en tire varnished surface and the inlaid design with a sheet ot tin or gold toil 5, and in many cases this sheet may be additionally utilized to at the same time supply part ot the inlaid design by iilling in the interstices between the pearls or other inlaid material.

F rom the foregoing it Will be apparent that I have evolved a. simple, inexpensive, labor-saving process ott great practica-bility tor the ornamentation ot glass by eiiectinp; inlaid designs or emblems 7 thereon. and although certain particular steps and materials have been specified, it is to be understood that the same may be modified or varied within the scope ot' the appended claims Without departing from or sacrificing any oty the principles ot this invention.

Haring nonv described my invention` what l desire to secure by Letters Patent is as set -forth in the following claims:

l. A process fdr the ornamentation ot glass consisting in building up the reverse surface 0f the glass by the application ot' a coating of hardening luid and providing rec .ses in said coating in the form ol? the desired design, subjecting the recesses to an application ot' transparent material, inlaj'ing the said recesses with pearls or the lil-:e and subjecting the inlaid material to pressure.

Q. A process olf ornamenting glass bj; inlaying a design thereon, cons sting ot snpei-imposingon the reverse surface ot theA glass tin foil in the form ot the design, covering the glass and toil with a coating ot hardening material, remoring the ting foil to provide recesses, applying a coating ot transparent adhesive fluid over the entire surface including the recesses. inlay-'ing the recesses, and subjecting the inlaid niaterial to su'l'licient pressure to embed the same in said recesses and transparent inaterial.

A process ot ornamenting lass by inlaying a design thereon, consisting oit' building up the reverse surface ot the glass by the application o a coating ol' hardening Huid, a pigment associated with said coating for providing a baci; ground 'lor said design, providing recesses in said coating in the form ot the desired design, subjecting the recesses to an application ot transparent material, inlaying the said recess s( and subjecting the inlaid material to pre-'- sure.

Il. A process ol ornainenting glass by inlaying a design thereon, consisting ot' building up the reverse surface ot the glass by the application ot' a coating ot' hardening pigmented tluid to provide a background for said design `l proriding recesses in said coating in the form ot' the desired design.

subjecting the recesses and the pigmented 1 material to an application o'l transparent material, inlaj'ing the said recessesT applying a color material orer the pigmented surface and the inlaid material, subjecting the inlaid and color material to pressure to enibed the color material in the interstices in tbe inlaid material7 said color n'iatcrial also forming a backing to encase the inlaid einblem and pigmented material between said color material and glass.
